New engine question

[Edwinh1234]

Got a brand new engine built. It is warming up here but every few nights it does get in the 20-30’s. Since it is a new engine & doesn’t have any water inside, does it need to be winterized while it sits in the jet ski? Thanks guys!

Lubricant is always suggested amongst the usual parts.

so am i good on the winterizing? Just lubricate it?

If it hasn’t been in the water or hooked up and ran on the water “hose”, block is essentially dry, everything should be ok.
Buy BR8ES solid tip plugs gapped at .22-.24 thousands, new fuel, clean RAVE’s, charge battery, ( tender ).
12.5 - 14.4 is sufficient. Crank, see what happens ..

The usual gremlins can show up depending on how the ski has been taken care of. Report back asap.

I hope it’s running perfect after what I’ve spent! Paid for the entire motor to be redone & a brand new carb. Plus replaced all the fuel lines, fuel selector, filters, all that good stuff.

I sent it off to a guy on eBay who had a couple thousand ratings for motor rebuilds. Had it back 2 days later for $1200. Comes with a warranty also. It’s a 717

This is all I got at the moment but the guy did a tremendous job. Everything looks extremely smooth. Found out my crankshaft snapped so he replaced that & my bottom casing had a ton of dings in it so he replaced it also. But everything was replaced. Probably gonna clean it up a bit & call it good.

Is the block or engine on a bench or in the ski?
Send a pic for reference

I have the engine out on a table waiting to be installed. I haven’t put it in yet

I gotcha!

Why is the bottom of the crankcase a different color than the top half?

Make sure you use the correct oil, those dark stained hoses are a sore thumb that the previous oil was wrong.

Lol it looks weird I know. My bottom crankcase was really beat up so the guy that rebuilt it used an extra one he had for me. It’s the correct size, just not the same color unfortunately.

When are you putting the motor in?

Big red flag! By the paint mismatch the bottom and top case halves are not the same.

You can not mix case halves. They are matched and line bored when torqued together at the factory. You have to replace them as a matched set.

I’ll actually message the guy now & ask why. Curious now. He has a whole business of just rebuilding engines. 5000 reviews 99.5%, all 5 stars so I just assumed he did good. Hopefully there’s a good reason, I’ll keep you updated.
